{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"A world choropleth map colors countries by their economy category, with an interactive color legend that filters which countries remain highlighted. Built with D3 v5, it uses `geoNaturalEarth1` projection with `geoPath` for geographic rendering, `zoom` for panning and scaling, and a `scaleOrdinal` with a spectral scheme for categorical colors. Data comes from TopoJSON world-atlas files merged with TSV metadata, and clicking a legend tick dims all non-matching countries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/114fb833789e4b4c84773866c3171b3c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
